Physical Properties of Wood Moisture Content/MC |
The amount of water contained in wood usually expressed as a percentage of the weight of the oven dry wood. |
|
|
One of the basic characteristics of wood Property of wood to absorb and remit moisture |
HYGROSCOPICITY |
|
|
Methods of determining moisture content |
1. Gravimetric or ovendry wood 2. Moisturer meter 3. Distillation method |
|
|
samples will be collected, weighed and later on overdried when repeated weighing after overdrying. 103 + -2 degree Celsius |
Gravimetric or over dry method |
|
|
Acquired apparatus in Gravimetric or oven dry method |
Weighing scale and oven |
|
|
Formula in getting the MC |
MC% = Wg- Wo / Wo × 100 |
|
|
Accurate within the range of 7-25 % moisture content Done by driving needle electrodes into wood and content |
Moisturer Meter |
|
|
Used in wood contains pitch Boiling of specimen in toulene to dissolve the pitch deposited. |
Distillation Method |
|
|
Type of Water in Wood |
Free water Bound of water Water of constitution |
|
|
Water present in cell cavities and first to be extracted from the food during drying |
Free Water |
|
|
The water contained in the cell wall |
Bound or hygroscopic water |
|
|
Water associated in the chemical structure and composition of the wood. It can not be removed without causing destruction of the wood. |
